Plasticity Region Genesjhp0940,jhp0945,jhp0947, andjhp0949ofHelicobacter pyloriin Isolates from Mexican Children

Background The genes jhp0940 , jhp0945 , jhp0947 , and jhp0949 belong to the plasticity region of the Helicobacter pylori genome. Due to their prevalence in isolates from patients with gastritis, duodenal ulcer, and gastric cancer, they have been proposed as markers of gastroduodenal diseases. These genes are associated with pro‐inflammatory cytokine induction through the NF ‐κB activation pathway. Nevertheless, the status of these genes is...
